Cisco Systems RV016, RV042G manual IPv6 Transition

IPv6 Transition 3

IPv6 Transition

When Dual-Stack IP is enabled on the Network > Setup page, a 6to4 tunnel is enabled by default for IPv6 packets via 6to4 source/destination addressing exchange. This feature allows the router to establish auto-tunnel in IPv4 network (or a real IPv4 Internet connection) across two independent IPv6 networks. Use the Setup > IPv6 Transition page to disable or enable this feature.

To open this page: Click Setup > IPv6 Transition in the navigation tree.

Check the box to enable the 6to4 tunnel, or uncheck the box to disable it.

NOTE Before navigating away from this page, click Save to save your settings, or click Cancel to undo them. Any unsaved changes are abandoned.

Next steps: For a typical deployment, such as setting up a 6to4 tunnel between your RV0xx Series router and a Cisco RV Series router at another site, you also should complete the tasks listed below.

•On the DHCP->Router Advertisement page, enable managed RA flags to support auto-configuration of connected devices. Verify that your IPv6 devices acquire 6to4 prefixes. The prefixes will be in the following format: 2002:<your WAN IP in hexadecimal format>::)

•Temporarily disable the router firewall for testing of your 6to4 tunnel. On the Firewall > General page, choose Disable. To test the tunnel, attempt to ping an IPv6 address at the remote location.

•After verifying the tunnel as described above, enable the firewall and add access rules on the Firewall > Access Rules page. For example, add a rule to allow all traffic through the WAN interface where the source is a single IP
